  Objective: In order to prevent single segment insertion skew when inserting a
  replicated table into random table we must ensure that the plan will spray
  the data randomly across all segments. We achieve this by filtering everthing
  except a single segment and then redistributing it to all other segments.

  DROP TABLE IF EXISTS test_replicated;
  DROP TABLE IF EXISTS test_randomly;
  CREATE TABLE test_replicated ( a text, b int ) DISTRIBUTED REPLICATED;
  INSERT INTO test_replicated VALUES ( 'a',1 ), ('b',2 ), ('c',3),('d',4);

  # Expect to have a Redistribute Motion on top of one-time result hash filter
  EXPLAIN CREATE TABLE test_randomly AS SELECT * FROM test_replicated DISTRIBUTED RANDOMLY;
                                          QUERY PLAN

  -------------------------------------------------------------------------------------------
   Result  (cost=0.00..0.00 rows=0 width=0)
     ->  Redistribute Motion 3:3  (slice1; segments: 3)  (cost=0.00..431.02 rows=1 width=12)
           ->  Result  (cost=0.00..431.00 rows=1 width=12)
                 One-Time Filter: (gp_execution_segment() = 0)
                 ->  Seq Scan on test_replicated  (cost=0.00..431.00 rows=1 width=12)
